Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30B is a genuine double-acting COMPACT cylinder (Ø80mm bore) whose extend end-position is set by an external M20×1.5 adjustment screw. You can dial the stroke anywhere from 15 to 45 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30B
The AirTAC SDAJ80X45-30B is a compact double-acting single-rod cylinder built for tight axial spaces, featuring a male-thread M22x1.5 piston rod and a PT3/8 air port. A fixed NBR bumper decelerates the piston near the end of travel, while the external M20x1.5 R adjuster screw lets you dial the extend stop down from the 45 mm maximum to 15 mm directly on the machine.
Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 2513.3 N of push at 0.5 MPa. The short riveted body saves valuable mounting depth where larger profile or round-body cylinders cannot fit, and the rod travels at speeds between 30 and 500 mm/s.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 45 mm |
| Adjustable range | 15 – 45 mm |
| Adjuster thread (R) | M20×1.5 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M14×1.5 F / M22×1.5 male (B) |
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Cushion | Fixed NBR bumper (both ends) |
The adjustment screw shortens the extend stroke by up to 30 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
Force matches a standard SDA of the same bore; the adjuster only sets the stop position, not the area. Actual usable force is lower than theoretical due to friction.

Where the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30B Is Used
Heavy Press Fitments
Dial in the 15-45 mm extend stop during initial tooling setup to precisely seat heavy bearings without cycling a fixed-length actuator.
Product Diverters
Adjust the male M22x1.5 rod extension on the fly to handle varying package widths on a packaging line without swapping hardware.
Vertical Lift Stops
Set precise upper travel limits for loads up to 128.1 kg, relying on the mechanical stop to prevent over-travel in lifting rigs.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30B the Right Cylinder?
When sizing this unit, stepping down to the SDAJ63 bore yields 1558.6 N of push at 0.5 MPa, whereas moving up to the SDAJ100 bore provides 3927 N. This 80 mm model is ideal for applications requiring a safe working load of roughly 1508 N (about 60 percent of its 0.5 MPa rating) or a vertical lift capacity near 128.1 kg with a 2:1 safety margin.
Choose this configuration if your fixture requires frequent on-site stroke tuning between 15 and 45 mm. Confirm your setup needs the male M22x1.5 rod end and note that this specific SKU lacks a piston magnet, meaning it cannot host reed or electronic switches. Finally, remember that a plain cylinder drifts when air is lost or a valve centers; the bumper and R screw decelerate travel but do not lock the load, so specify an external rod lock or pilot-operated check valve for holding requirements.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 15–45 mm
- ✓ Force at your working pressure
- ✓ Access to reach the R adjuster
- ✓ Magnet (S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the M20×1.5 adjuster after setting the stroke.
- check Avoid side load on the piston rod.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30B FAQ
This 80 mm bore cylinder delivers 2513.3 N push and 2267.8 N pull at 0.5 MPa, 3518.6 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum of 513 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa at speeds of 30-500 mm/s.
Turning the M20x1.5 R screw shortens the extend stroke by up to 30 mm, providing an adjustable range of 15 to 45 mm. This mechanism sets the mechanical stop position and does not alter the cylinder's output force.
